Regional difference in total factor productivity and spatial features : Empirical Analysis on the Basis of a Sectoral Translog Production Function

This paper applies a sectoral production function of translog type to Japanese regional data, introducing the variables of spatial attributes as the determinants of the technological level in the region, and thereby analyses the regional difference in total factor productivity.     

Non‐Negative Quantity Constraints and the Duration of Punishment

In an oligopoly supergame, firms face an obvious technological constraint: the positivity of their production quantities. Applicability of single‐period optimal punishment hinges critically upon the degree of supermodularity in the stage game, as well as upon the positivity constraints on prices and/or quantities. If both prices and quantities are constrained to be positive, then the relevant multi‐period punishment prescribes securitylevel payoffs (where individual rationality binds) when and only when the game is perfectly supermodular, i.e. is either a Bertrand supergame with perfect substitute products or a Cournot supergame with perfect complement products.

Income class, modal choice, and urban spatial structure

This paper analyzes the impacts of urban transportation system changes and income changes on the welfare of people and on the urban spatial structure, in a setting where the income level differs between two groups, and two transportation modes compete with each other in a city. It is demonstrated that an improvement in some transport facility will not necessarily increase the welfare level of every household, and, at times decreases the welfare of some households. It also is argued that under particular situations, an improvement in a particular transport mode may produce a contraction in the city size rather than an expansion. Similarly, an increase in income of one group might have an adverse effect on the welfare of another income group as a result of competition in the land market.     

Interdependence and Managing Conflict with Sub-Contractors in the Construction Industry in East Asia

In contrast to traditional assumptions about Asian conflict management, interdependence may induce cooperative approaches to conflict rather than avoidance or competition. Findings from supervisors on 216 subcontractors in Korea, Japan, and Hong Kong support the hypotheses that interdependence leads to cooperative conflict which results in constructive conflict which in turn helps the subcontractor contribute to the main contractor. However, competitive and avoiding conflict were found to be useful in Taiwan. Results were interpreted as suggesting that the theory of cooperation and competition offers the potential for strengthening conflict management in East Asia and that cooperative conflict, rather than avoiding, may reinforce feelings of interdependence in East Asia.     

Inertia in the key currency

This paper empirically analyzes inertia in the position of the dollar as the key currency. We extend a money-in-the-utility model to one with parallel international currencies. We use an extended model to estimate a parameter in the utility function. Also, given the estimated parameter, we simulate a relation between depreciation and share of the dollar. The result indicates that the share of the dollar will not decrease even if the dollar depreciates at a moderate rate. Thus the dollar will keep its position as the key currency – inertia works in the key currency.     

RJVs in product innovation and cartel stability

Abstract. We characterise the interplay between firms' decision in product development undertaken through a research joint venture (RJV), and the nature of their ensuing market behaviour. Participant firms in an RJV face a trade-off between saving the costs of product innovation by developing similar products to one another, e.g., by sharing most of the basic components of their products, and investing higher initial efforts in product innovation in order to develop more distinct products. We prove that the more the firms' products are distinct and thus less substitutable, the easier their collusion is to sustain in the marketing supergame, either in prices (Bertrand) or in quantities (Cournot). This gives rise to a non-monotone dependence of firms' product portfolio upon their intertemporal preferences.

The skewness risk premium in equilibrium and stock return predictability

In this study, we investigate the skewness risk premium in the financial market under a general equilibrium setting. Extending the long-run risks (LRR) model proposed by Bansal and Yaron (J Financ 59:1481–1509, 2004) by introducing a stochastic jump intensity for jumps in the LRR factor and the variance of consumption growth rate, we provide an explicit representation for the skewness risk premium, as well as the volatility risk premium, in equilibrium. On the basis of the representation for the skewness risk premium, we propose a possible reason for the empirical facts of time-varying and negative risk-neutral skewness. Moreover, we also provide an equity risk premium representation of a linear factor pricing model with the variance and skewness risk premiums. The empirical results imply that the skewness risk premium, as well as the variance risk premium, has superior predictive power for future aggregate stock market index returns, which are consistent with the theoretical implication derived by our model. Compared with the variance risk premium, the results show that the skewness risk premium plays an independent and essential role for predicting the market index returns.     

Total Factor Productivity of the Japanese Rice Industry

We calculate partial factor productivity and total factor productivity (TFP) indices for rice production using panel data across 42 Japanese prefectures from 1996 to 2006, and perform panel unit root tests of TFP convergence across prefectures. We find that during this period, the partial factor productivity growth rates for capital, land and materials stagnated at the aggregate national level, as did the TFP growth rate, despite a large increase in labor productivity. We also identify evidence of a convergence in TFP across Japanese prefectures.
